lm_sensors on ASUS A8N-Sli Motherboards--Here's How

I am using kernel-2.6.15-gentoo-r1. As this version seems to work extremely well with this hardware, I recommend that you update to this kernel. (Caveat: My system is only a few days old, but I've yet to find something awry.)

I upgraded my motherboard BIOS to version 1009, the latest stable BIOS.

Here are the 2.6.15-gentoo-r1 kernel parameters:

Code:

Device Drivers --> I2C Support
<*> I2C Support
<*> I2C device interface

Device Drivers --> I2C Support --> I2C Algorithms
<*> I2C bit-banging interfaces

Device Drivers --> I2C Support --> I2C Hardware Bus support
<M> Nvidia nForce2, nForce3, and nForce4

Device Drivers --> Hardware Monitoring support
<*> Hardware Monitoring support
<M> ITE IT87xx and compatibles

Or, if you prefer them in config file format:

Code:

CONFIG_I2C=y
CONFIG_I2C_CHARDEV=y
CONFIG_I2C_ALGOBIT=y
CONFIG_I2C_ISA=m
CONFIG_I2C_NFORCE2=m
CONFIG_HWMON=y
CONFIG_HWMON_VID=m
CONFIG_SENSORS_IT87=m

Compile and install the kernel per instructions. Reboot.

This will give you the following kernel modules:

Code:

i2c_nforce2
i2c_isa
hwmon_vid
it87

The rest are compiled directly into the kernel. We'll have the lm_sensor system load the modules automagically for us, so do nothing to /etc/modules.autoload.d/kernel-2.6

Install lm_sensors. (I am using version 2.9.2)

Code:

emerge lm_sensors

Edit /etc/conf.d/lm_sensors

Code:

LOADMODULES=yes

INITSENSORS=yes

MODULE_0=i2c_nforce2
MODULE_1=i2c_isa
MODULE_2=it87

Now the only thing left to do is to configure the sensors themselves. Don't ask me how I got the following information because it's a conglomeration of multiple sensors.conf files I've found on the Net. This works damned well on this motherboard. I stumbled on serveral files to help me and figured out the best combination.

Edit /etc/sensors.conf

Code:

chip "it87-*" "it8712-*"

# The values below have been tested on Asus CUSI, CUM motherboards.
# Voltage monitors as advised in the It8705/It8712 data sheets
label in0 "VCore 1"
label in1 "VCore 2"
label in2 "+3.3V"
label in3 "+5V"
label in4 "+12V"
label in5 "-5V"
label in6 "-12V"
label in7 "Stdby"
label in8 "VBat"

# Ignore unsupported or flakey interfaces
ignore vid

ignore in1
ignore in5 # comment out to try it out
ignore in6 # comment out to try it out
ignore in7
ignore in8

# Scale the voltages
# Note: in5 and in6 don't seem to work, but these are their scalings
compute in0 -0.05 + @ , @ + 0.05
compute in3 ((6.8/10)+1)*@ , @/((6.8/10)+1)
compute in4 ((30/10) +1)*@ , @/((30/10) +1)
compute in5 (7.67 * @) - 27.36 , (@ + 27.36) / 7.67
compute in6 (4.33 * @) - 13.64 , (@ + 13.64) / 4.33
compute in7 ((6.8/10)+1)*@ , @/((6.8/10)+1)

# Ranges (Adjust per your system)
set in0_min 1.5 * 0.85
set in0_max 1.5 * 1.05
set in1_min 2.4
set in1_max 2.6
set in2_min 3.3 * 0.95
set in2_max 3.3 * 1.05
set in3_min 5.0 * 0.95
set in3_max 5.0 * 1.05
set in4_min 12 * 0.95
set in4_max 12 * 1.05
set in5_max -5 * 0.95
set in5_min -5 * 1.05
set in6_max -12 * 0.95
set in6_min -12 * 1.05
set in7_min 5 * 0.95
set in7_max 5 * 1.05

# Temperature
# 2 = thermistor; 3 = thermal diode; 0 = unused
set sensor1 2
set sensor2 2
set sensor3 2

# Temp names and scales
# Adjust "over" and "low" as you see fit
label temp1 "CPU Temp"
set temp1_over 60
set temp1_low 15
label temp2 "C/S Temp"
set temp2_over 60
set temp2_low 15
label temp3 "M/B Temp"
set temp3_over 50
set temp3_low 15

# Fans (only two fans supported) Adjust "min" as you see fit
label fan1 "CPU Fan"
label fan2 "Cha1 Fan"
set fan1_min 800
set fan2_min 800
ignore fan3

Next, bring up lm_sensors.

Code:

/etc/init.d/lm_sensors start

You should see the modules automagically load.

Code:

* Loading lm_sensors modules...
* Loading i2c-nforce2 ... [ ok ]
* Loading i2c-isa ... [ ok ]
* Loading it87 ... [ ok ]
* Initializing sensors ... [ ok ]

Check the modules by typing "lsmod":

Code:

Module Size Used by
it87 23588 0
i2c_isa 4800 1 it87
i2c_nforce2 6848 0
hwmon_vid 2496 1 it87

Notice that it87 has brought in the hwmon_vid module.

Now look at your sensors, just type in "sensors" at the prompt.

Here's my output:

Code:

it8712-isa-0290
Adapter: ISA adapter
VCore 1: +1.29 V (min = +1.23 V, max = +1.52 V)
+3.3V: +3.25 V (min = +3.14 V, max = +3.47 V)
+5V: +4.81 V (min = +4.76 V, max = +5.24 V)
+12V: +11.97 V (min = +11.39 V, max = +12.61 V)
CPU Fan: 2678 RPM (min = 799 RPM, div = 8)
Cha1 Fan: 1548 RPM (min = 799 RPM, div = 8)
CPU Temp: +33 C (low = +15 C, high = +60 C) sensor = thermistor
C/S Temp: +36 C (low = +15 C, high = +60 C) sensor = thermistor
M/B Temp: +39 C (low = +15 C, high = +50 C) sensor = thermistor

Note that my PSU has a low 5v rail. It hasn't caused any problems yet, but I have contacted Seasonic about it.

I've played around with the -12v and -5v sensors, but they don't seem to be reporting anything meaningful. Here's what sensors says about them:

Code:

-5V: -4.90 V (min = -5.27 V, max = -4.78 V)
-12V: -13.64 V (min = -12.60 V, max = -11.42 V) ALARM

These voltages are not monitored, so just leave them out.

Hope this helps people get things working. This may also work well on other, similar ASUS nForce4 motherboards. Try it.

Comments and corrections solicited.

Hey look at my results, I got A8N-E, but ...

Code:

it8712-isa-0290
Adapter: ISA adapter
VCore 1: +1.07 V (min = +1.28 V, max = +1.58 V) ALARM
VCore 2: +0.00 V (min = +2.40 V, max = +2.61 V) ALARM
+3.3V: +3.25 V (min = +3.14 V, max = +3.47 V)
+5V: +4.89 V (min = +4.76 V, max = +5.24 V)
+12V: +12.03 V (min = +11.39 V, max = +12.61 V)
-5V: -4.78 V (min = -5.27 V, max = -4.78 V) ALARM
-12V: -13.64 V (min = -12.60 V, max = -11.42 V) ALARM
Stdby: +4.89 V (min = +4.76 V, max = +5.24 V)
VBat: +3.10 V
CPU Fan: 927 RPM (min = 0 RPM, div = 8)
Cha1 Fan: 0 RPM (min = 0 RPM, div = 8)
Chip Fan: 4218 RPM (min = 998 RPM, div = 8)
CPU Temp: +35°C (low = +15°C, high = +60°C) sensor = thermistor
C/S Temp: +32°C (low = +15°C, high = +60°C) sensor = thermistor
M/B Temp: +27°C (low = +15°C, high = +50°C) sensor = thermistor

+5V is also defected a little , as well as -5 and -12 .. perhaps wrong readings ? need adjustment ?

I too have an A8N-E, i would like to know what your final values are for sensors.conf.

My +5v reading is in line with that reported by my BIOS Setup. So, I tend to believe that my PSU has a low +5v rail.

Note that your negative voltages are likely no good, just like mine. I suggest that you "ignore" them in sensors.conf.

I didn't realize that there were three temp sensors until I played around with things. Apparently, there is because these temps are also in line with those reported in the BIOS Setup, although BIOS does not report the Northbridge (C/S) temp. This is an important one since if the Sli Premium's passive Northbridge cooling isn't working that chip would get very hot, very quickly.

just a tip:

if you edit /etc//modules.d/it87

Code:

cat /etc/modules.d/it87
options it87 fix_pwm_polarity

you would be able to control fan speeds manualy or by fancontrol script (use pwmconfig first)

how come I do not have this file?

Here is what I currently have:

Where did you get that /etc/modules.d/it87 ?

Moreover, I never was succesfull in setting Cool N Quite on my AMD because I was assuming that fan speed autoadjust to CPU temperature. Is this still the same or has it changed or so?

Thank you,

This sensors.conf working just fine with new sys-apps/lm_sensors-2.10.3
Just remember to compile kernel with k8temp support

Code:

cat /etc/sensors.conf
chip "it8712-*"

label in2 "+3.3V"
label in3 "+5V"
label in4 "+12V"
label in5 "-5V"
label in6 "-12V"
label in7 "Stdby"
label in8 "VBat"
ignore in1
# Compute Value
compute in3 ((6.8/10)+1)*@ , @/((6.8/10)+1)
compute in4 ((30/10) +1)*@ , @/((30/10) +1)
compute in5 (7.67 * @) - 27.36 , (@ + 27.36) / 7.67
compute in6 (4.33 * @) - 13.64 , (@ + 13.64) / 4.33
compute in7 ((6.8/10)+1)*@ , @/((6.8/10)+1)
# Temperature
label temp1 "M/B Temp"
label temp2 "CPU Temp"
label temp3 "Chase Temp"
# Fans
ignore fan2

chip "k8temp-*"
